that is *very* neat. i have a conceptual version using a 'class' 
userdata, where you would say

require "class"
local animal = class{ table describing class : functions and methods}
local cat = animal{local attribs etc}

simply because userdata functions always call __index, so read-only is 
the default.

but your way is better.
